Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.
The summary also stated that 2024 was the second consecutive year with the hottest global temperature, surpassing 2023 by +0.12 °C. [3] 21 January: a study published in Nature Climate Change concluded that at least 30% of the Arctic has become a net source of carbon dioxide. [4]
Note: A 2024 paper by RJ Graham et al. argues that silicate weathering is far less-temperature-dependent than initially thought, and that falling carbon dioxide levels are unlikely to lead to the death of life on Earth before the Sun's increasing temperature finally ends it in +- 1.6 billion years.
The production of free oxygen by cyanobacterial photosynthesis eventually led to the oxygen catastrophe that ended Earth's second atmosphere and brought about the Earth's third atmosphere (the modern atmosphere) 2.4 billion years ago. Carbon dioxide concentrations dropped from 4,000 parts per million during the Cambrian period about 500 million ...
The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office. The visualization is a product of a simulation called a “Nature Run.”
RCP 2.6 is a "very stringent" pathway. [6] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.
The growth rate from 1990 to 1999 averaged 1.1% per year. Between the years 2000–2009, growth in CO 2 emissions from fossil fuel burning was, on average, 3% per year, which exceeds the growth estimated by 35 of the 40 SRES scenarios (34 if the trend is computed with end points instead of a linear fit). [20]
Four climate change scenarios, based on 2015 data. [5] [6] Left: emissions pathways following the scenarios of (1) no policy, (2) current policy, (3) meeting the governments’ announcements with constant country decarbonization rates past 2030, and (4) meeting the governments’ announcements with higher rates of decarbonization past 2030.
